STRAW-STACKER.

SPECIFICATION forming part of Letters Patent No. 712,311, dated October 28,1902.

Application filed January 24, 1902. Serial No. 91,084. (No model.) I

To all whom it may concern:

Be it known that I, ABRAM M. KOLP, a citizen of the United States, residing at Salunga, in the county of Lancaster and State of Pennsylvania, have invented a new and useful Straw-Stacker, of which the following is a specification.

My invention is an improved straw-stacker for threshing-machines and grain-separators; and it consists in the peculiar construction and combination of devices hereinafter fully set forth and claimed.

In the accompanying drawings, Figure 1 is a perspective view of a straw-stacker embodying my improvements, showing the same attached. to a threshing machine and grainseparator and disposed in inoperative position, with the upper hinged section of the trunk disposed over the top of the threshingmachine casing. Fig. 2 is a longitudinal sectional view of the same, showing the stacker disposed in operative position. 7

In the embodiment of my invention here shown the inner end of the elevator-trunk 1 is pivoted on the projecting ends of the shaft 2, which carries the roller 3, andwhich shaft is mounted at the outer side of the turn-table frame 4. A roller 5 has its bearings near the inner side of the turn-table frame, and the said roller 5, together with the roller 3, carries and operates an endless feed-apron 6. The latter and the turn-table are so disposed at the rear end of the threshing-machine casing that the straw discharged from the latter falls upon the feed-apron 6 and is by the latter carried outwardly in the direction indicated by the arrow in Fig. 2. The shaft 2 is provided at one end with a pair of sprocketwheels 7 8. In practice the turn-table frame is provided on its under side with .a fifthwheel 9, which is mounted on a base-frame 10, the said base-frame being supported on a pair of beamsll, which project from the rear end of the threshing-machine. A shaft 12, which is journaled in bearings secured to the said beams 11, has a pulley 13 at one end which is driven by a belt 14 from a pulley 15 on a power-shaft 16,.with which the threshing-machine is provided. The shaft 12 is provided with a miter gear-wheel17 near its center, which is engaged by a similar gear 18 on the lower end of a shaft 19, the latter being journaled in suitable bearings, as at 20,

and is disposed centrally with relation to the fifth-wheel. The miter gear-wheel 21 is secured to the upper end of said shaft 19 and is engaged by a similar wheel 22 on a shaft 23. turn-table frame and is provided at one end with a sprocket-wheel 24. It will be understood from the foregoing that the shaft 23 may be revolved by the power transmitted thereto from the shaft 16 irrespective of the position of the pivotally-mounted turn-table. An endless sprocket-chain 25 connects the sprocket-Wheel 24 and the sprocket-wheel 7, and hence the shaft 2, and therefore the feedapron, are driven, as will be understood.

The elevator-trunk comprises the inner section 1 and the outer section 1", which is hinged thereto, as at 26. It will be understood that since the inner end of the elevator-trunk is pivotally mounted on the shaft 27 is here shown as attached to the outer section of the'elevator-trunk, passed over a direction-sheave 28, and having its inner end attached to a suitable winch 29, by means of The latter shaft has its bearings in the which the elevator-trunk may be inclined as gles to the axis of the trunk. The said endless traveling carrier is provided with crossslats 38. On one end of the shaft 34 is a sprocket-wheel 40.

The outer section of the elevator-trunk is provided with a bottom 41, which is preferably made of galvanized sheet-iron, but within the scope of my invention may be made of any other suitable material. The outer portion of the inner section of the elevator-trunk is provided with a bottom 42, which closes its lower side. The outer portion of the bottom of the elevator-trunk converges outwardly from the lower lead of the carrier 30 at the discharge end of the trunk, as at 43, thus facilitating the discharge of material from the stacker. The sides of the outer trunk-section at the discharge end thereof are correspondingly widened, as at 44, and hence the discharge end of the stacker-trunk may be supported on the floor of a barn or on any other object when the machine is in operation.

That portion of the lower side of the inner section or end of the elevator-trunk which is not covered by the bottom is closed by the upper lead of an endless traveling supplemental carrier 45. The same comprises an endless apron 46, a roller 47, which is journaled in bearings 48, that operate in guideways 49 in the sides of the trunk near the inner end thereof, and a roller 50, which is journaled in fixed bearings in the sides of the inner section of the elevator-trunk and is disposed at some distance from the inner end of the bottom 42. The upper lead of the supplemental carrier, which is disposed under the lower lead of the carrier 30 at the inner side thereof, forms a portion of the bottom of the elevator-trunk, as will be understood from an inspection of Fig. 2. A roller 52 is disposed between the roller and the inner end of the bottom 42, is journaled in suitable bearings under the sides of the elevator-trunk, and is provided at one end with a pulley 53. The shaft of the roller 50 has a pulley 54, and an endless belt 55 connects the pulleys 53 54, and hence power may be conveyed from the roller 50 to the roller 52, so that the latter may be rotated when the supplemental carrier is in operation. The shaft 50 is provided at one end with a sprocket-wheel 55. An idler 57 is journaled on a stub-shaft 58, that projects from one side of the elevator-trunk near the inner end thereof, and an endless sprocket-chain 56 engages and connects the sprocket-wheels 8, 55, 40, and 57. Hence power is conveyed from the shaft 2 to the carrier, the supplemental carrier, and the roller 52.

The bearings 48, which are movable in the guideways 49,are engaged bysprings59,which move the said bearings, and hence the roller 47 at the inner side of the supplemental carrier, toward the carrier 30, and thereby the inner side of the supplemental carrier is yieldably supported and pressed toward the carrier and is adapted to move outwardly therefrom when a considerable bulk of straw is between said carrier and the supplemental carrier. The inner side of the latter is disposed under the discharge side of the feed-apron G, and hence the straw is fed from the latter between the carrier 30 and the supplemental carrier. The upper side of the roller 52 moves in the same direction as the upper side of the supplemental carrier and prevents chaff from falling between the supplemental carrier and said roller. The coaction of the lower lead of the carrier 30 and the supplemental carrier and bottom of the elevator-trunk is such that the straw is carried upwardly through the elevator-trunk and discharged at the outer end thereof. The outer side of the carrier is movable toward and from the bottom thereof by reason of the shaft 35 being journaled in movable bearings, as liereinbefore described. The said roller by gravity tends to remain in the position shown in Fig. 2; but when an accumulation of straw is between the carrier and the bottom of the elevatortrunk the outer side of the latter by moving outwardly from the bottom of the trunk at the discharge end of the trunk facilitates the discharge of the straw, as will be understood.

The supplemental carrier is in practice provided with transverse slats to facilitate the engagement thereof with the straw. The transverse slats on the carrier 30 are serrated on their outer sides to reduce friction between them and the bottom of the trunk, as in practice the lower lead of the carrier sags so that the said slats bear directly on the bottom of the trunk when there is no straw between the carrier and the trunk-bottom.

Having thus described my invention, I claim- 1. In a straw-stacker, the combination of an elevator-trunk closed on its lower side, an endless traveling carrier in said trunk, having its lower lead disposed above the bottom thereof, and an endless traveling supplemental carrier under the lower intake side of the carrier, said supplemental carrier being yieldably'supported under the carrier and movable automatically therefrom, by accumulation of material between the intake portions of the carrier and supplememental carrier, for the purpose set forth, substantially as described.

2. In a straw-stacker, the combination of an elevator-trunk having a closed bottom, and an endless traveling carrier in said trunk over the bottom thereof, that portion of the said carrier at the discharge end of the trunk being movable by gravity toward the bottom of the trunk and adapted to move outwardly therefrom to facilitate the discharge of material, substantially as described.

3. In a straw-stacker, the combination of an elevator-trunk, an endless traveling carrier therein, said trunk having a closed bottom and said carrier having its lower lead it I over the bottom of the trunk, an endless trav- In testimony that I claim the foregoing as eling supplemental carrier, under the inner my own I have hereto affixed my signature in on of the lower lead of the carrier and the presence of two Witnesses.
